“I use these IEM's at work and during travel, it's very easy to transport with the small metal case. It was difficult to achieve the good isolation, i tried 10+ pair of silicon cushions and i finally got one which fits perfectly into my ears. These are very sensitive IEM's, if you hate source noises stay away from them, i hear little hiss even with my desktop amp/dac combo Corda Aria, probably...” --Lewzke

“
Ultimate ears metro.fi range are often overlooked on these forums. There is a simple reason for this, they are not worth the price they quite often retail at. They are, however, frequently on special offers and very good deals, i've even seen them being given away with other things costing only about £50. Obviously when earphones are on special offer they should be compared to others in their...” --Marcus_C

For over 17 years we’ve been crafting the world’s finest custom in-ear monitors for discerning music listeners and industry pros. Traditionally, the “custom” in “custom in-ear monitors” refers to personally molded shells that fit you and only you. However, with the UE Personal Reference Monitors we’re taking customization to a whole new level.
As the...

This is my very first pair of custom IEMs after trying almost all of the high end universal IEMs -- SE530, UE Super Fi 10, Etymotics etc. The sound of these UE11 Pros is superior in every way to all of the universal ones I had, but even more important they stay in my ear and provide a proper seal. Since my ear canals get very narrow, I found it very difficult to get any of my universals to...” --alyanm

Quite nice if you like/need bass. Lots of it.
This phone is a weird construction that falls somewhat short of what it could be. If only UE had refined the bass performance, done something about the highs and added some midrange.
At any rate, theres bass aplenty if that is what you are looking for. Bass extends deep and punches hard. I often find myself EQing the bass down and...” --Hakone

These were my first IEMs, so obviously at first I thought that these were the pot of gold at the end of the rainbow. But after awhile...
Bass is clear and punchy. Highs are pretty clear but high mids can get a bit muddy IMO. I'll be honest, it takes a lot of work to get these to fit, and once you do, they are really uncomfortable, at least for me.

Absolute steal at this price.
Should have given a review on these a long time ago but unnecessary because for one simple fact.
You either get a good fit on these and experience pure nirvana or dislike it for any possible conceived ideas.
It's quite inaccurate to listen to people's opinions as well.
Some people clearly state that the IE8 is much better than the Tf-10 but the Se530 is...” --Sil3nce

“Edit: So UE has announced the new update to the UERM, the UE Reference Remastered... 1 day after my review. Pretty ironic but it is what it is haha. So I guess this review may be more a tribute to the past than I had initially intended it to be as the UERM is now officially discontinued. The Story Behind the Name: ...” --Cotnijoe

“This is my first written review on Head-Fi, so please take everything with a grain of salt, but I am going for a detailed review here, and I intend on doing more in the future, so please feel free to comment on anything I can do to improve! Anyway, let's dive right in! A little about me: A little over a year ago, some switch flipped inside of me, and I discovered the...” --cvbcbcmv
